A '''klobuk''' is an item of non-liturgical [[clergy|clerical]] clothing worn by Orthodox Christian [[monk|monastics]] and [[bishop]]s. It is composed of a [[kamilavka]] covered with an epanokamelavkion (veil).
In the Greek and Arabic Churches, all [[bishop]]s regardless of rank wear an identical plain black klobuk. Generally speaking, [[metropolitan]]s in the Slavic Churches wear white klobuks, while [[bishop]]s and [[archbishop]]s wear black ones. [[Archbishop]]s who have been awarded this honor and [[metropolitan]]s also wear a small jewelled cross on the front of their klobuk. This is not the case, however, in the Churches of [[Church of Serbia|Serbia]] and [[Church of Bulgaria|Bulgaria]], where [[metropolitan]]s use black klobuks, and the white klobuk with the jewelled cross is reserved for the first hierarch of the Local Church (but in the [[Church of Bulgaria|Bulgarian Church]], [[metropolitan]]s may also be awarded jewelled crosses for their klobuks). The practice of [[Church of Bulgaria|Bulgarian Church]] coincides with that of the [[Church of Romania]].
The [[Patriarch]] of [[Church of Russia|Moscow]] and all Rus' wears a white klobuk that is rounded on top, decorated with embroidered images of [[seraphim]], and surmounted with a cross. This is sometimes called a cowl in English, although this is inexact. Also, the [[Archbishop]] of Karelia and [[Church of Finland|Finland]] wears a white klobuk as head of an [[autonomous]] Church.
